Splitting hydrogen and oxygen from water using conventional electrolysis techniques requires considerable amounts of electrical energy. But green plants produce oxygen from water efficiently using a catalytic ...

(PhysOrg.com) -- Collective, or coordinated behavior is routine in liquids, where waves can occur as atoms act together. In a milliliter (mL) of liquid water, 1022 molecules bob around, colliding. When a bre ...

(PhysOrg.com) -- We drink water, bathe in it and we are made mostly of water, yet the common substance poses major mysteries. Now, University of Utah chemists may have solved one enigma by showing how cold ...

Scientists often find strange and unexpected things when they look at materials at the nanoscale -- the level of single atoms and molecules. This holds true even for the most common materials, such as water.

(PhysOrg.com) -- The process of splitting water into pure oxygen and clean-burning hydrogen fuel has long been the Holy Grail for clean-energy advocates as a method of large-scale energy storage, but the idea faces technical ...

Many kinds of algae and cyanobacteria, common water-dwelling microorganisms, are capable of using energy from sunlight to split water molecules and release hydrogen, which holds promise as a clean and carbon-free ...

High in the sky, water in clouds can act as a temptress to lure airborne pollutants such as sulfur dioxide into reactive aqueous particulates. Although this behavior is not incorporated into today's climate-modeling ...

Less than 1 percent of Earth's water is drinkable. Removing salt and other minerals from our biggest available source of water—seawater—may help satisfy a growing global population thirsty for fresh water ...

Simple improvements to a bland-looking catalyst could change biofuel refining; the challenge is discovering how the catalyst truly works. Led by scientists at Pacific Northwest National Laboratory, a team ...

Scientists at the US Department of Energy's Oak Ridge National Laboratory are learning how the properties of water molecules on the surface of metal oxides can be used to better control these minerals and ...
